DERRlCK-SWlNGING ATTACHMENT FOR HOISTING-ENGINES.

SPECIFICATION forming part of Letters Patent No. 707,851, dated August 26, 1902,

Application filed Tune 7, 1901. Serial No. 63,524. (No mcdeL To all whom it may concern.-

Be it known that I, ASHERLAMBERT, a citizen of the United States,residingat 117 Poinier street, in the city of Newark, county of Essex, State of New Jersey, have invented certain new and useful Improvements in Derrick- Swinging Attachments for Hoisting-Engines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

The object of the present invention is to furnish an improved construction for the hoisting apparatus that is used in connection with a boom-derrick, so that the derrick may be swungin eitherdirection with morepromptness and accuracy than is attainable by the usual means.

The invention consists of a swing drum or winch mounted to rotate in connection with the hoisting-drum and connected by frictionwheels with the same gearing which rotates the hoisting drum, such friction-Wheels be- 7 ing arranged and operated to reverse the rothe same distance apart as the frames of the tation of the swing drum or winch at pleasure. Two ropes are wound in opposite directions upon the swing drum or winch and attached at their outer ends to the bull-wheel upon the derrick. The drum or winch to receive the two ropes may be combined with any ordinary portable power-hoister by mounting the drum or winch in a suitable mannerto be driven by the gearing of the hoisting-drum. For applying the invention to portable hoisting-machines already in existence the swing drum or winch and its supporting-frame and gearing may be constructed as a separate attachment to be mounted upon the same beams or skids as the bed of the portable hoister. An ordinary hoister is provided with tWo parallel side frames across which the drum-shafts are mounted in suitable bearings, and the swing-drum is most conveniently combined with the hoisting-drums by mounting it also upon a shaft extended across between two parallel side frames, With such side frames hoister, so that they may be bolted to the same timbers or skids. The frame for the swing-drum is provided with suitable gearing to connect such drum with the gearing of the hoisting-drums and to suitably reduce the speed, and one or more friction-wheels are preferably interposed in the gearing between the hoisting-drums and swing-drum, so as to easily stop and start the swing-drum.

In practice when combining my improvement with existing hoisters I provide one of the hoisting-drum shafts where it overhangs its bearing with a friction-wheel and provide the gearing of the swing-drum with two friction-wheels adapted to connect with the same and arranged to turn the swing-drum respectively inopposite directions. The movement of the friction-wheels is controlled by a single hand-lever, and the ropes from the bull-wheel upon the derrick are wound in opposite directions upon the swing-drum at the opposite ends of the same, so that the tension of the swinging-ropes is constantly uniform, and

the stoppage or reversal of the swing-drummay be completely controlled by the movement of a single lever.

The invention will be understood by reference to the annexed drawings, in which- Figure 1 is a perspective View of a boomderrick with the hoisting apparatus connected thereto. Fig. 2 is a plan of the hoisting apparatus with my improvements, and Fig. 3 is a side elevation of the same. Fig. 4 is a side view of the reversing-lever, showing the friction-wheels and their connectingpinions. Fig. 5 is anend View of thereversing-lever with the friction-wheels h and their connecting-gears Z. Fig. 6 is a side View, and Fig. 7 an edge view, of the bell-crank q. Fig. 8 is a plan of the frames for the hoisting-drums and the swing-drum; and Fig. 9 is an e1evation of the same, the frames being secured upon skids T. L

a designates the post of the derrick, b the boom, and c the bull-wheel upon the bottom of the post. The hoister is shown with the usual drums at and d for hoisting the load and the boom,and the so-called swing-drum is designated a and connected by ropes f and f with the opposite edges of the bull-wheel c. The ropes are wound in reverse directions upon opposite ends of the drum e, so that the turning of'the drum in any degree operates positively to turn the bull-wheel and swing the boom. The drum 6 is shown connected by gear-wheels g and g and friction-wheels h and i with the shaft of the hoisting-drum (Z, but may be reversely connected with any rotating shaft upon the hoister.

The shaft of the drum d is shown provided with the usual overhung windlass w, formed at its innerend with a grooved friction-wheel v}, and

a shaft 7c is shown mounted between the drums d and e and connected with the drum 6 by a pair of gears g. I have termed the wheel 1' a driving friction-wheel in theclaims, and any friction-wheel connected with the hoisting-drumto rotate therewith would operate with the same effect. The shaft k is provided outside of its bearing 70 with awheel g and with a swinging leverj, which carries two interlocking pinions '1, one of which meshes with the wheel 9'. Each of the gears l rotates upon a stud it (upon the lever-arm j) with a, grooved friction-wheel h, and a correspondingly-grooved friction-wheel is attached to the shaft of the drum d, with its grooves contiguous to those of the wheel It, so that the movement of the reversing-lever in opposite directions presses the one or the wheels t' to the swing drum or winch. The

reverse-lever j is pivoted upon the shaft 70 with the wheel g, and one of the studs h is necessarily set at a greater distance from the .shaft 75 than the other, so that only one of the pinions Z meshes with and drives the wheel g. A hand-lever m, having a latch 11 and notched segment 0 to control its position, is mounted upon a shaft m and connected by a link 19 and a bell-crank q with the free end of the reverse-lever and serves to hold the'reVerse lever in its intermediate or neutral position, in which no motion is imparted to the drum 6 or to press either of the friction-wheels it against the friction-wheel Land thus rotate the swing-drum e in either direction. In Fig.

' 3 the upper friction-wheel h is shown nearer to the gear-wheel g than is the lower frictionwheel and is pressed upon the wheel 7,'and the pinion Zof such friction-wheel meshes directly with the gear-wheel g, thus rotating the swing-drum e in the direction of the arrow e The reverse position of the lever j would throw'the lower friction wheel h against the wheel 1;, and its motion would be transmitted to the gear-wheel g through both the pinions l, thus reversing the rotation of the swing-d rum to the direction indicated by the arrow a The bell-crank g, which connects the link p with the reversmg-leverj, is shown journaled upon the overhung 'end of the shaft 6', which carries the swing-drum e;

but it is immaterial where the reversing-leverj or bell-crank q is pivoted, provided the operation is secured as described herein.

such gearing,-I do not limit myself to the precise construction shown in the drawings,

although'I have made specific claims thereto.

It will be observed in Fig. 1 that the hoisting-machine frame and the appliance for swinging the derrick are secured upon skids T, which hold them in their operative rela tion to one another and make them readily removable together.

It will be observed in Fig.3 that the drum and all the mechanism which connects the same with the friction-wheel 2' are mounted upon a frame R, separate from the frame S, which carries the hoisting-drums d d, and the appliance for swinging the boom thus constitutes a separate attachment, which may be applied to any hoisting-machine by bolting it upon skids T in the proper position and furnishing the hoister with a friction-wheel i. The ordinary hoisting-machine and the swingdrum mechanism may thus be built separately and combined together where the hoistingdrum is to be used in connection with a -boom-derrick, and any hoister which is destitute of a swing-drum can be readily furnished with one by securing also the frictionwheel 2' for attachment to the hoisting-drum shaft. Such friction-wheel is readily furnished by exchanging the Windlass 20 upon the hoister for a windlass provided with the Turnbuckles t are shown connected to the adjacent ends of the frames R and S to hold them in their operative relation and to adjust the pressure of the friction-Wheels h and 72/ upon the friction-wheel 7 Such adjustable connection is very desirable where the swinging devices are constructed separately from the hoisting devices and are sustained upon a skid, as the bolts which fasten the two devices to the skid are liable to yield under the pressure of the friction-wheels. If the swingdrum were mounted upon the same frame as the hoisting-drum, such frame would hold the parts rigidly in connection; but Where the swing-drum and its frame and gearing are made as a separate attachment to be connected with a hoisting-machine by fastening upon skids it is obvious that some means, like the turnbuckles, is necessary to prevent the pressure of the friction-wheels from forcing one of the frames away from the other. Any means may be used which operates the same as the turnbuckles to hold the frames R and S in their operative relations. Where the frame of the swing-drum is constructed to combine with the frame of the hoistingdrum upon the same timbers, it is preferable that the frames B should be constructed the same distance apart as the frames S, and I have made claim to such a construction of the frames. It is obvious that my attachment for swinging the drum is applicable to any hoister provided with drum for raising the manently with the gearing of the other drums,

so as to run continuously, thus involving great wear of such parts. In my construction all the gearing for the swing-drum is disconn ected from the gearing of the hoisting-drums when the swiug'drurn is not in use, and the friction-gearing and the gears g and g are then wholly preserved from wear. A winch w is shown overhung upon the shaft of the hoisting-drum d, and both the winches w and u" can thus be kept in continuous motion and utilized at any moment without the slightest interference from the attachment which constitutes the swinging device.

It is obvious that a winch which is overhung from its bearings can be used with two ropes wound in opposite directions and con nected to a bull-wheel to swing the derrick in thedesired manner, providedsuch winch is connected with the hoisting-drum by gearing which rotates it at a slower speed than such drum and which is provided with frictionwheels to reverse the motion by the manipulation of a single hand-lever. My invention is shown herein in a convenient form for application as a separate attachment to hoisting-machines; but the rotation of the swinging drum or winch at a speed below that of the hoistingdrum and the use of the two ropes and friction-gearing in the manner described constitute the essence of the invention, which may therefore be carried out without the use of the precise construction herein described.

Having thus set forth the nature of the invention, what is claimed herein is 1. In a hoister, the combination, with a hoisting-drum, of the means for swinging a boom-derrick, consisting of the swing-drum e having the swing-ropes f, f wound thereon in reverse directions, a friction-wheel upon the shaft of the hoisting-drum, a lever pivoted upon the frame of the hoister, two friction-wheels geared together and mounted upon such lever, and suitable gearing connecting one of such friction-wheels with the swing-drum.
